I've reported some issues related to mediaplugin filter:
MDL-26727 and MDL-26729, so I can't wait for your improvements
Also, it would be very useful if you can code into the filter some option for deactivating the embedding mechanism as per-file level. The reason behind this is the following: imagine that you embed a video in one resource page, but for some reason the user isn't able to view it embedded. In this case is very useful to provide a plain link to the file for the user to download it directly. I'm thinking of a code like:
<p>Please watch the following video:<br />
<center><a href="a.link.to/the_video.flv">The video</a></center></p>
<p>If you're experiencing problems viewing the video above, please <a href="a.link.to/the_video.flv?embed=none">download it directly</a>.</p>
The key will be supporting some sort of extension mechanism similar to the one used to specify the size of the embedded video.
